A ray of light strikes a smooth surface and is reflected. The angle of incidence is 35°.

A smooth surface produces regular reflection, which follows the law of reflection: the angle of reflection equals the angle of incidence. Since the angle of incidence is 35°, the angle of reflection is also 35°. Therefore, choice C, “Rays will follow the law of reflection, so the angle of reflection will be 35°,” is correct.
